To aZZ whom it may concern: I

Be it known that 1, JOHN W. PrIrLLrr-s, a citizen of the United States,residing at Sil- .ver City, in the county of Lyon, State of raters andmore particularly to that class of separators which are utilized toseparate ores from liquids.

The primary ob ect of the invention is to provide a separator which willefliciently same.

perform its function in completely separating the-ore and liquidintroduced therein.

The invention includes among other features novel means for removing theliquid and ores from the machine during the proccss of separation.

The device is of such construction that. the mixture will not hedirected against the walls of the separator until it has entirelyentered the same, the means for so directing the liquid being a rotarydisk which is located adjacent the middle of the device.

As a further novel feature, the-invention includes means for removing anseparated ore which may collect in the bottom of the se arator.

- 11 tlie'accompanying drawings, Figure 1' is a view in elevation of theseparator. Fig.

2 is a vertical sectional view through the Fig. 3 is a top plan view ofthe same.- Fig. 4 is a horizontal sectional view on the line -i-:i ofFig. 2. Fig. 5 is a vertical sectional View through the lower end of thecasing of the separator, showing a slightly modified form oftheinvcntion, and, Fig. 6 is a detail perspective view of the scraper.

Referring more specifically to the drawings, the numeral 10 denotes theupper portion of thc'frai'ne in which my separator is mounted. A shaft11 has a hearing in the frame 10 and upon. the said shaft,-al ovc thel'ra n c, is secured a pulley 12 around which is engaged a bolt 13 froma drive shaft (not Shown) l):\' l1l0i1HS 0f which the shaft 11 isrotated. To prevent upward movement of the shaft 11 in its bearing inthe frame 10,

a collar 13 is secured upon the shaft by means of a set screw 14. andbears a ainst,

the under side of the frame 10.

The separator includes a casing com--- posed of major and minorfrusto-ccnical sections 15 and 16 respectively, each oi which isprovided at its base with an annular flange 17 by means of which the ensare united. its upper end with an inwardl directed annular flange 18 .tothe under side of which is secured .the upturned ends of arms 19 whichradiate from a collar 20 secured to the shart 11;. in any suitablemanner. These arms 19 support the casing as will be readily understoodand cause rotation of the said casing with the shaft 11. Formed in theupper end of the minor section 16 at its junction with the flange 18 isanannular series of openings 21 which constitute an outlet for theliquid separated from the mixture introduced into the separator as willbe hereinafter fully explained. Secured in any desired manner to theunder side of the frame 10, is an annular trough 22 which.

has its inner. side lying close to the sideof the minor section 16 belowthe openings 21 and its outer side 23 extending with its upper edgeabove the plane occupied hythe series of openings. -Leading from thesin-- nular trough is a spout .Z with'which is connected a pipe 25through which. the Waste liquid is discharged. in order that the wasteliquid as it is discharged through the openings 21 may be directed intothe trough 22, I provide an annular deflector plate 26 which is securedat its inner edge to the flange 18 and which has its'outer edge directeddownwardly, as at 27, into the trough 22 and in the direction of theouter side 25 of the'same.

It will, oi course, be understood that the raw material to be separatedis introduced into the separator from thetopand in order of therasingadjacent its upper end, an annular shield 28 is provided, the saidshield edge of the annular iangc 18 and depends therefrom, and has itswall tapered upwardlyv annularly as at .27, to receive the upper end TheseetionlG is provided at to prevent the same from reaching the sides ofa sloeve-shaftglSi, which is disposed upon the shaft- 11 -arid has. itslower end resting 5 being secured at its 11 per end to the inner upon acollar 29 which is secured by means of a set screw 30 to the said shaft11. Secured upon the sleeve-shaft 28 adjacent its lowerv I I upper andouter edges with upwardly directed extensions 33 to the outer edges ofwhich.

and the said wings proper are secured s irally disposed blades 34 whichcontact with the inner face of the major section. The extended portions33 terminate in a plane In above the junction ,of the two sections andthe up er ends of the blades 34 are tapered to con orm to the taper ofthe wall of the minor section 16 to prevent lodging of ore in angleformed by the connection of the two 2 sections. Each of the wings 32 isprovided with an opening 35 to allow free circulation of the liquidduring the process of separation.- Secured to-the shaft 28 and the upperedges .of the wings 32 in a plane below that occupied bpthe lower edgeof the shield, is a circular te 36 upon which the raw material, isthrown, by means of the said annular shield 28. From this plate thematerial is thrown by centrifugal force upon the sides of the casmg andis acted upon by the spirally arranged blades 34, which force the wasteliquid upwardly and through the openings 21 and allow the heav particlesof ore to descend. The taper of t e minor section 16 is such that 3should any particles of ore be .carried by the I liquid against theinner face of this section, the said particles will by reason of their Igravity and the centrifugal force exerted, drain back to be acted uponby the blades 34. 4 In the'preferred form of my invention, the wings 32and blades 34 terminate short of the lower end of the maj or section 15and this said end 1s provided witn an inwardly directed an: nular ange37 upon which the particles of ore are designed to lodge. Secured to thesleeve 28 is a scraper 38 which is formed of sheet metal and has itsblade ortion bent longitudinally at right angles to orm a portion 39which lies vertically with res and a portion 40 whichlies parallel tothe said flange. I The portion 39 is notched as at 41, I to receive theflange 37 with the lug 42, formed by notchin the said plate, yingagainst the under si e of the flange 37 to pre- ,-vent vertical movementof the scraper. The

ortion of the blade located above the notch.

1s ada ted to scrape the surface of the flange 37 an the portion 38 ofthe scraper revents the ore from running over the said b ade portion 39.curved in'a direction opposite to the direction of rotation of thecasing ,of the separator in order to direct the accumulated ore from theflange 37 into a suit-able receptacle (not shown) 1 I trough.

ect to the flange 37 The scraper has its outer end In the form shown inFig. 5, the spiral blades extend to the extreme lower end of the majorsection 15 and deposit the sepa- I rated ore directly into a suitablereceptacle, the flange 37 in this'case being omitted.

I In practice, the pulleys 12 and 31 are of such size that shaft 11 andsleeve shaft 28' will be rotated at different speeds, the shaft '28 morerapidly than the shaft 1 1.
